$PECIIEIGA'EION forming part of Letters Patent No. 695,123, dated March11, 1902.

Application filed August 3,1901. Serial No. 70,715. (No specimens.)

To all whom it may concern:

Be it known that I, GEORGE EDWARD JAMEs STREET, of no occupation, asubject of the King of Great Britain, residing at Elm Villa, KnightsPark, Kingston, county of Surrey, England, haveinvented certain new anduseful Improvements in Illuminating Compounds, of which the following isa specification.

This invention has reference to illuminating compounds for consumptionin fairy or bucket lamps or lamps for ornamental illumination; and itsobject is to produce a new type of oil which is peculiarly adapted foruse in such lamps.

,It is well known that lamps of the kind in question consuming any ofthe oils hitherto used for same are very dirty in burning and smoke tosuch an extent as not only to give devoted a great deal of time inexperiment ing with the object to produce a compound which shouldovercome these drawbacks, and I have at length succeeded in producing atype of oil or compound which eifects this object in a most satisfactorymanner. Theimproved type of illuminant burns with a clean brilliantsmokeless flame, evolving no unpleasant smell andproducing a mostpleasing eifect from an illuminating point of View. Lamps charged withthe improved compound will continue to burn with unimpaired brilliancyand cleanliness until the charge is entirely consumed, and, moreover,they will burn for a much longer time than is possible with any of theoils hitherto usedfor such lamps.

The improved type of illuminant which constitutes the subject of thisinvention consists of a mixture of lard-oil and neats-foot oil with orWithout camphor. I prefer to mix these ingredients in about thefollowing proportions: three-fourths pint of lard-oil, onefourth pint ofneats-foot oil, and when camphor is used one-half ounce camphor. Itwill, however, be understood that I do not limit myself to these exactproportions, which may be varied. V

.What I claim, and desire to secure by Letters Patent, is-- 1. Anilluminating compound for fairylamps, bucket-lamps orlamps forornamental illumination, containing a mixture of lardoil and neats-footoil.

2. An illuminating compound for fairylamps, bucket-lamps or lamps forornamental illumination, consisting of a mixture of lard oil, neats-footoil and camphor.

In witness whereof I have hereunto signed my name in the presence of twosubscribing witnesses.

GEORGE EDWARD JAMES STREET.
